These include: season (cold-dry, hot-dry, and warm-wet), pen type (open and sealed), age (in days and weeks), stocking density of layers per pen, and daily amount of feed consumption.
Among other things, the measures now being weighed by the Chilean Congress, which are expected to be passed before April, would thin the density of salmon pens, where overcrowding has contributed to the virus's spread, and reduce the use of antibiotics.
My teacher had us use fine Rapidograph pens to make dot drawings with the density of the dots creating the shading, and I also tried drawing with white pencil on black paper.
Each treatment contained 4 randomly assigned pens of 9 animals stocked at a density of 2.73 m/head.
The turkeys were kept on deep litter at a stocking density of 2.5 bird per m and eight birds were allocated within one pen.
For transfection, cells were seeded at the density of 3×106 per well of six-well plate in SFM without Pen-Strep.
Mr. Alonso, who is Long Island-based, used a ballpoint pen as if it were a brush, applying layers of tiny black and blue marks until he got the density of light and texture he was looking for.
On the morning of each journey, the animals were loaded at 8 00 h into two fan-ventilated pens (n = 6 animals/pen) on the lower deck of an air suspension articulated transporter at a stocking density of 1.02 m2 per animal, and transported by road.
One h before the arrival of the animals a broth with a pathogenic strain of E. coli (O147; K89, STb) was spread to a density of 2 × 10CFU per square meter on the floor of empty and previously disinfected pens.
A sustained density of sound.
